Possible malfunctions
- The AKIRA LCT-30KXSTP TV does not turn on at all. The control lights do not light or flash. On the remote control and the buttons on the control panel does not respond.
Often in such cases, the AUKXD24V.PCB power module is faulty. It is necessary to measure the output voltages in the secondary circuits, and if they are absent, check the operability of the power switches (FQP18N50, FQP7N80) of the converters and rectifier diodes for a short circuit.
In case of breakdowns in the secondary circuits, the converter can operate in a short circuit mode, and during a short circuit in the elements of the primary circuit, the mains fuse usually breaks.
The breakdown of Mos-Fet keys used in pulsed sources is often caused by malfunctions of other elements, for example, power supply, frequency-setting, damper ... as well as elements of the Negative Stabilization Feedback. PWM microcircuit (PWM) MC33260D (PFC), NCP1203, NCP1377DR2 (PWM flyback 8pin) can also cause a malfunction of the power switch of the converter and is checked by replacement.
- There is no image, but there is sound and reaction to the remote control. Or for a second, the image may appear immediately after switching on.
The defect can be caused by problems in the nodes or elements of the backlight of the display, or in the power supply of the lamps or the inverter.After checking all the electrolytic capacitors of the filters that are involved in the power supply to the inverter, you must ring in its converter power keys for breakdown and secondary windings of transformers for an open.
If in diagnosing a malfunction, it is necessary to disable the inverter protection, there is a risk of failure of the power elements of the inverter, and special care is required during work, and after they are finished, it is necessary to restore the protection circuits for further safe operation of the TV by the owner in normal mode.
- The indicator on the front panel blinks, the TV does not turn on in the operating mode, it does not respond to the remote control.
Repair or diagnostics of the TVM3001103 motherboard should begin by checking the stabilizers and power converters needed to power the chips and matrix. If necessary, update or replace the software (software). In cases of complex repairs of MB (SSB) and in the presence of the necessary skills and equipment, sometimes it may be necessary to replace its chips VPC3230D, 24C16, K4S641632C, AD9883A, MAX232A, PW113, 29LV800D and other possible faulty components. Malfunctions associated with the application of BGA soldering technologies are usually easily diagnosed by the heating method.
The malfunction of the tuner FI1256MK2 is established after checking the software and all supply voltages at its terminals. The data exchange of the tuner with the processor via the I2C bus can be controlled by an oscilloscope.

Attention! Users and owners of LCT-30KXSTP televisions who do not have the appropriate qualifications, knowledge and experience are strongly discouraged from attempting self-repair in order to avoid negative consequences that could lead to complete non-repairability of the device.

PSU Advanced
The LCT-30KXSTR model uses the AUKXD24V.PCB power supply unit using the PFC (Power Factor Correction) node - an active filter of the highest harmonics of the current consumption. In fact, it is a step-up converter based on the MC33260D PWM controller, which eliminates the charge current of the electrolytic capacitor of the rectifier filter directly from the network through open diodes when its charging current is determined by its reactance.
As a result of the operation of the converter, the envelope of the high-frequency pulses of the input current of the converter will repeat the shape and phase of the input voltage. The health of the PFC node can be indirectly judged by the presence of an increased constant voltage (about + 380V) on the capacitor of the rectifier network in operating mode.

General recommendations for repairing TV LCD
Possible manifestations of defects
- The TV AKIRA LCT-42MT02ST does not turn on and does not show any signs of turning on, it does not respond to the control buttons or the remote control.
Typically, with such manifestations, the defect is caused by faulty elements in the main power module of the MLT198L. It is necessary to measure its output voltages and, in case of their absence, check the serviceability of power switches and rectifier diodes in the converters for possible breakdown.
In case of breakdowns of semiconductors in secondary circuits, the converter can usually work abnormally in the short circuit mode, and during short circuit in the power elements of the primary circuit, the mains fuse often breaks.
Mos-Fet keys used in switching power supplies usually fail due to a malfunction of other elements that can put it out of operation in key mode or provoke an excess of the maximum current or voltage. These can be circuits supplying the PWM controller, damping or frequency-setting circuits, or elements of OOS (negative feedback) in the stabilization circuit. PWM controllers (PWM) MC0628R, NCP1653A (PFC), LD7550, in the absence of external damage and short circuit between the terminals, are checked by replacing with obviously good ones.
- There is no image, but there is sound and reaction to the remote control. Or for a second, the image may appear immediately after switching on.
The defect can be caused by problems in the nodes or elements of the backlight of the display, or in the power supply of the lamps or the inverter. If all the electrolytic capacitors of the filter for the power supply of the inverter are working, you should make sure that the lamps are working, then you need to check the converter keys and the secondary windings of the transformers.
Sometimes, for diagnostic purposes, inverter protection must be disabled. In such cases, special care must be taken during work, and the protection circuits should be restored immediately after the repair is completed.
- The indicator blinks or lights constantly, the TV does not turn on, does not respond to the remote control.
Repair or diagnostics of the TV3201-ZC01-02 motherboard should be started by checking the stabilizers and power converters needed to power the microcircuits and matrix. If necessary, update or replace the software (software). In some cases, to repair the MB (SSB) board, it may be necessary to replace the chips - MST9X88LD, 25X40VNIG, HY5DU281622FTP-5, STA540SA with new or obviously working ones. In cases where BGA technologies are used, defects are usually localized by the heating method.
If there is no reception of television channels, but the TV is working properly from external devices, first of all you need to check the voltage of the tuner JS-6H2-12 and update the software. The pulses from the I2C bus must be controlled with an oscilloscope.

General recommendations for repairing TV LCD
AKIRA from the chassis, like other televisions, it is advisable to start repairing with a careful examination of the external and internal elements and modules. Visible damage to elements can sometimes indicate the direction of the search for a defect even before the necessary measurements are taken. Elements with visible damage, for example, capacitors swelled up after boiling the electrolyte, charred resistors in certain nodes of the circuit, as well as ring cracks in solders will help the master to guess the causes and possible consequences of the malfunction.
In the case when the LCT-D26MT05ST does not turn on, does not respond to the remote control and buttons on the front panel, does not blink bulbs and does not show any signs of operability, the MIP260B power supply module is probably faulty in this case. If it is serviceable under such manifestations, it is necessary to check the power supply stabilizer (converter) of the processor on the motherboard.When diagnosing and repairing the power supply, after replacing the swollen capacitors of the secondary rectifier filters (if any), it is necessary first of all to check the mains fuse. When it is broken, the power elements of transistors and rectifier bridge diodes should be checked for avalanche (thermal) breakdown.
If a breakdown of the power switch is detected, it should be remembered that in a switching power supply (IIP) it does not fail by itself for no reason that should be sought by checking other elements of the primary circuit - electrolytic capacitors, a PWM controller, which can only be checked replacement, as well as other semiconductor elements (diodes, transistors, zener diodes).
If the AKIRA LCT-D26MT05ST does not have an image, but there is sound, there is a possibility of a malfunction of the backlight or power converter. You should also make sure that the electrolytic capacitors of the secondary rectifiers of the common power supply are working. It is necessary to take into account that in cases of inverter protection shutdown (in order to be able to diagnose) there is a risk of failure of the inverter power elements and take special care. After carrying out repairs, the protection circuit must be restored for further safe operation of the TV.
If the motherboard MSDV2601-ZC01-01_C P / N: 303C2601073 is faulty, first of all it is necessary to check all the linear stabilizers or power converters of its chips, and also, if necessary, update the software. Sometimes you can check the health of MB only by replacement.

Attention to the owners! Attempts to repair the TV AKIRA LCT-D26MT05ST on its own are not recommended by the manufacturer and can lead to serious negative consequences!

General recommendations for repairing TV LCD
Possible manifestations of defects
- AKIRA LCT-D26MT02ST does not turn on, the indicators on the front panel do not light or flash. The TV does not respond to the control buttons and the remote control.
Most likely in this case, the main switching power supply (IIP) MLT666 is faulty. It is necessary to measure its secondary output voltage, and in case of their absence, check the health of the power switches (18N50, 6N60C) of the converters and rectifier diodes for a short circuit.
In case of breakdowns in the secondary circuits, the converter can operate in a short circuit mode, and during a short circuit in the elements of the primary circuit, the mains fuse usually breaks.
The breakdown of Mos-Fet keys used in pulsed sources is often caused by malfunctions of other elements, for example, power supply, frequency-setting, damper ... as well as elements of the Negative Stabilization Feedback. PWM chip MC0628R, L6562D (PFC), OB2262 (PWM SOT23-6 62719) can also cause a malfunction of the power switch of the converter and is checked by replacement.
- There is no image, there is sound, it responds to the remote control, the channels are switched. In some cases, the image appears when you turn on and immediately disappears.
These manifestations can be triggered by a power module, or by defects in the inverter, as well as a distortion of the currents in the lamps due to their uneven wear. If all the electrolytic capacitors of the filter according to the inverter power supply are serviceable, you should make sure that the lamps are working, then you need to check the converter keys and the secondary windings of the transformers.
If in diagnosing a malfunction, it is necessary to disable the inverter protection, there is a risk of failure of the power elements of the inverter, and special care is required during work, and after they are finished, it is necessary to restore the protection circuits for further safe operation of the TV by the owner in normal mode.
- The TV does not enter the operating mode, does not respond to the remote control. The indicator on the front panel lights constantly or blinks.
Repair or diagnostics of the DVD motherboard should begin by checking the stabilizers and power converters needed to power the chips and matrix. If necessary, update or replace the software (software). If it is not possible to replace the MB board (SSB), you need to check the health of its elements - W25X40, 24C32, STA5405A, IS42S16100C1-7TL, EN25T80. Defective components should be replaced.
The malfunction of the JC-6H2 / 121 tuner is established after checking the software and all the supply voltages at its terminals. The data exchange of the tuner with the processor via the I2C bus can be controlled by an oscilloscope.

Attention TV owners! Attempts at self-repair of AKIRA LCT-D26MT02ST are not recommended by the manufacturer and can lead to serious negative consequences!

Panel restoration (matrix repair) ------------------>  V260B1-L04

 The MLT666 power module is installed in the LCT-D26MT02ST TV using the PFC (Power Factor Correction) scheme acting as an active filter to eliminate the higher harmonic components of the current consumption. The boost converter based on the L6562D PWM controller does not allow the input rectifier filter's electrolytic capacitor to be connected to the network directly through open diodes, when the reactance (about 15-30 ohms at a frequency of 50 Hz) determines the charge current. As a result of the conversion, the charging current of the capacitor will be determined in such a way that the envelope of the high-frequency pulses of the input current will repeat the phase and shape of the sine wave of the input voltage. The health check of the PFC unit is carried out by measuring the DC voltage on the capacitor of the rectifier network. In operating mode, it should be around 380V, in standby approximately 300V.

General recommendations for repairing TV LCD
Possible malfunctions
- AKIRA LCT-37PBSTP does not turn on, the indicators on the front panel do not light or flash. The TV does not respond to the control buttons and the remote control.
In the vast majority of such cases, a malfunction is detected in the KAS200-5S241812XLS power supply module. It is necessary to measure its secondary output voltages, and in case of their absence, check the serviceability of the power switches of the converters and rectifier diodes for a short circuit.
In case of breakdowns in the secondary circuits, the converter can operate in a short circuit mode, and during short circuit in the elements of the primary circuit, the mains fuse usually breaks.
Mos-Fet keys used in switching power supplies usually fail due to a malfunction of other elements that can put it out of operation in key mode or provoke an excess of the maximum current or voltage. It can be supply, damper circuits, or elements of OOS (negative feedback) stabilization. The reason for the breakdown of the power switch may be PWM (MLM) PWM ML4800CS, CP1002PN. It is checked only by replacement with a known good one.
- There is no image, there is sound, it responds to the remote control, the channels are switched. In some cases, the image appears when you turn on and immediately disappears.
The defect can be caused by problems in the nodes or elements of the backlight of the display, or in the power supply of the lamps or inverter. If all the electrolytic capacitors of the filter according to the power supply of the inverter are working, make sure that the lamps are working, then you need to check the converter keys and the secondary windings of the transformers.
If in diagnosing a malfunction, it is necessary to disable the inverter protection, there is a risk of failure of the power elements of the inverter, and special care is required during work, and after their completion it is necessary to restore the protection circuits for further safe operation of the TV by the owner in normal mode.
- The indicator blinks or lights constantly, the TV does not turn on, does not respond to the remote control.
Repair or diagnostics of the 782-L37W25-6900 motherboard should begin by checking the stabilizers and power converters needed to power the microcircuit and matrix. If necessary, update or replace the software (software). In cases of attempts to repair the MB (SSB) board, it is necessary to check the health of its elements - M30620SPGP, W29C040P-90B, 24LC32AI, TVP5147, K4D263238F-QC50, SII9011CLU, MSP 3410G BB V3, TPA3008D2 which may require replacement with new ones. If a BGA processor is installed, there is a possibility of a violation of the soldering of the contacts of its conclusions with the board (it is diagnosed by heating).
If there is no reception of television channels, but the TV is working properly from external devices, first of all you need to check the voltage of the tuner JB-6B2 / 122A2-A2 x2 and update the software. The pulses from the I2C bus must be controlled with an oscilloscope.

TV users and owners need to remember that attempts to self-repair an AKIRA LCT-37PBSTP TV without the appropriate qualifications and necessary experience can lead to serious negative consequences!

General recommendations for repairing TV LCD
Possible malfunctions
- AKIRA LCT-32V82ST does not turn on, the indicators on the front panel do not light or flash. The TV does not respond to the control buttons and the remote control.
In such cases, the fault should be sought first in the QAL0748-001 power supply module. It is necessary to measure the output voltages in the secondary circuits, and in case of their absence, check the serviceability of the power switches of the converters and rectifier diodes for a short circuit.
In case of breakdowns in the secondary circuits, the converter can operate in a short circuit mode, and during a short circuit in the elements of the primary circuit, the mains fuse usually breaks.
The breakdown of Mos-Fet keys used in pulsed sources is often caused by malfunctions of other elements, for example, power supply, frequency-setting, damper ... as well as elements of the Negative Stabilization Feedback. PWM chip 203D6 (8), L6562D (PFC), KIA339F (14) can also cause a malfunction of the power switch of the converter and is checked by replacement.
- There is no image, there is sound, it is responding to the remote control. Or immediately after turning on for a second, the image may appear and immediately disappear.
The defect can be caused by problems in the nodes or elements of the backlight of the display, or in the power supply of the lamps or the inverter.After checking all the electrolytic capacitors of the filters that are involved in the power supply to the inverter, you must ring in its converter power keys for breakdown and secondary windings of transformers for an open.
If in diagnosing a malfunction, it is necessary to disable the inverter protection, there is a risk of failure of the power elements of the inverter, and special care is required during work, and after they are finished, it is necessary to restore the protection circuits for further safe operation of the TV by the owner in normal mode.
- The TV does not turn on, does not respond to the remote control. The indicator blinks or signals standby mode.
Repair or diagnostics of the JUG7.820.121 motherboard should begin by checking the stabilizers and power converters needed to power the chips and matrix. If necessary, update or replace the software (software). Often, the MB (SSB) card must be replaced in case of complex malfunctions that are difficult to detect. When trying to repair, you should check its elements - SVP AX68 7668 LF / 7632LF, A FBB02, QH8Y0, 0812 / TAIWAN, 20GFB803F525002, HY5DU281622FTP-4, TDA9886TS, 74HCT4052D, PS201, 74VLC14AD642, 1410, 1410, LAX, 1411D, 1111D replace chips with new ones. Some malfunctions can be associated with the use of BGA soldering technologies in modern Main Board. Typically, such defects are detected by local heating of the chip.
Before changing the AFT7 / W103G tuner, if it is not possible to tune to television channels, make sure that there are supply voltages that must be measured at the corresponding tuner pins and check the software for correctness. The pulses of the data exchange of the tuner with the processor can be controlled by an oscilloscope
Attention to users! Self-repair of the AKIRA LCT-32V82ST TV without the appropriate qualifications and the necessary experience can lead to its complete non-repairability!
One of the typical defects of the AKIRA LCT-32V82ST TV option 1 may occur in the V315B1-l01 C2 panel.
External manifestations: color distortion in the image as a negative in the image, light tones predominate. Typically, in such cases, the AS15-G gamma corrector is faulty. Another indicator of its malfunction is an excessively strong heating, which in practice allows you to do without measuring voltage gradations of gray.
In most cases, replacing the AS15-G solves the problem.

It should be remembered that similar symptoms can cause faults in the column drivers of the panel, which is usually indicated by interference in the form of even vertical stripes on the screen. Then, after replacing the AS15-G, the situation does not change. Drivers are in loops and cannot be replaced. In this case, it is necessary to replace the glass panel.

PSU Advanced
The LCT-32V82ST model uses a QAL0748-001 power supply unit using the PFC (Power Factor Correction) node - an active filter of the highest harmonics of the current consumption. In fact, it is a step-up converter based on the L6562D PWM controller, which eliminates the charge current of the rectifier filter's electrolytic capacitor directly from the network through open diodes when its charging current is determined by its reactance.
As a result of the operation of the converter, the envelope of the high-frequency pulses of the input current of the converter will repeat the shape and phase of the input voltage. The health of the PFC node can be indirectly judged by the presence of an increased constant voltage (about + 380V) on the capacitor of the rectifier network in operating mode.

General recommendations for repairing TV LCD
Possible manifestations of defects
- The AKIRA LCT-32MT05ST TV does not turn on and does not show any signs of operability at all. There is no reaction to the remote control and control buttons from the front panel.
With such manifestations, a malfunction is likely to be detected in the MLT666 power supply module. It is necessary to measure the output voltages in its secondary circuits, and if they are completely absent, check the serviceability of the power switches (18N50, 6N60C) and rectifier diodes for possible breakdown (short circuit).
In case of any breakdown of semiconductors in the secondary circuits, the converter can usually work normally in emergency short circuit mode. There are no output voltages. And with a short circuit in the power elements of the primary circuit, as a rule, the mains fuse breaks and less often the current sensor at the source of the key.
Mos-Fet power switches, used in switching power supplies, sometimes fail due to a malfunction of any other elements that can put it out of operation in key mode or create an excess of the maximum permissible parameters of the switch. These can be elements supplying the PWM controller, frequency-setting or damping circuits, or negative feedback elements in the stabilization circuit. PWM controllers MC0628R, L6562D, OB2262, in the absence of visible damage or frank fault between the terminals, are checked by replacing with new ones, or obviously working.
- There is no image, there is sound, it responds to the remote control, the channels are switched. In some cases, the image appears when you turn on and immediately disappears.
These manifestations can be triggered by a power module, or by defects in the inverter, as well as a distortion of the currents in the lamps due to their uneven wear. After checking all the electrolytic capacitors of the filters that are involved in the power supply of the inverter, it is necessary to ring in its converter the power switches for breakdown and the secondary windings of the transformers for an open.
If in diagnosing a malfunction, it is necessary to disable the inverter protection, there is a risk of failure of the power elements of the inverter, and special care is required during work, and after they are finished, it is necessary to restore the protection circuits for further safe operation of the TV by the owner in normal mode.
- The indicator blinks or lights constantly, the TV does not turn on, does not respond to the remote control.
Repair or diagnostics of the motherboard MSDV2601-ZC01-01 should begin by checking the stabilizers and power converters needed to power the chips and matrix. If necessary, update or replace the software (software). In some cases, to repair the MB board (SSB), it may be necessary to replace the chips - CPU: MST9E19A; Spi flash: W25X40; AT89C2051; CPU: MST9E19A; SOUND: STA540SA for new or obviously working. In cases where BGA technologies are used, defects are usually localized by the heating method.
Before changing the JS-6H2 / 121 tuner, if it is not possible to tune to television channels, make sure that there are supply voltages that must be measured at the corresponding tuner pins and checked for correctness. The pulses of the data exchange of the tuner with the processor can be controlled by an oscilloscope

General recommendations for repairing TV LCD
TV AKIRA LCT-32MT04ST, like many other electronic devices, it is advisable to start repairing by inspecting all external and internal elements. Specific external damage to some elements can sometimes indicate further actions to determine the malfunction of the TV and localize the defect before the necessary measurements are taken. Experienced repairmen are often aware of the causes of the defect and possible consequences, for example, from ring cracks in the soldering of the leads of the elements, as well as from swollen capacitors or resistors burnt to coal dust and other external signs of certain malfunctions.
Sometimes the AKIRA LCT-32MT04ST TV simply does not turn on. No control lights on the front panel are lit or blinking, the TV does not respond to the remote control and does not make any sounds or any signs of life when turned on. The most likely cause of the malfunction is the failure of the MLT666 common power module. If it is working properly, you must check the standby batteries on the Main Board. After checking the mains fuse and power elements of the primary power supply circuit, it should also check the absence of a short circuit in the loads of the secondary rectifiers.
If the power keys of the pulse converter are not equal, you should pay attention to other elements in their bundling, which may be the result or cause of their breakdown.
If, when you turn on the TV, the image appears and immediately disappears, or is initially absent when you turn on, but there is sound and other functions work, there is a high probability of a malfunction of the inverter (power converter for the backlight). In such cases, the lamps, the inverter and the common power module are subject to verification, in which the electrolytic capacitors of the rectifier filter supplying the inverter should be checked. When disabling protection in order to enable the diagnosis of a malfunction, special care should be taken, and after completion of all repair work, it is necessary to restore the circuit and the inverter protection for further safe operation of the TV.
Repair of the motherboard MSDV2601-ZC01-01 C must begin with the diagnosis and verification of all linear stabilizers and power converters of its microcircuits. Sometimes it may be necessary to update the software (software) - flashing FLASH or EEPROM.
If a JS-6H2 / 121 tuner is suspected of malfunction, first of all, it is necessary to verify the correctness of the software, as well as the presence of the required voltage levels and data exchange pulses with the processor via the I2C bus at the corresponding tuner pins.

Once again, remind users! Attempts to self-repair a TV AKIRA LCT-32MT04ST without the appropriate qualifications and experience can lead to its complete non-repairability!
